Determining Product Quality of Valve Manufacturers
Determining Product Quality of Valve Manufacturers
(OP)
Considering how most of the well know domestic manufacturers of high quality valves have been bought out by conglomerates, how is one to know who is making the top-of-the-line products these days? I get a myriad of feedback from O&M personnel and distributors, but rarely get the opportunity to hear the opinions of other consulting engineers. I would like to hear opinions (and the reasons behind them) on who is making the best valve for the applications below:
Butterfly (shutoff) and Globe (throttling) for hydronic service
Gate (shutoff) and Globe (throttling) for steam service
Also, have you had any experience using high performance butterfly for steam shutoff? The reps seem to be pushing this, but I have my misgivings.
Please include both manual and automatic control valve maufacturers in your response.
Thanks in advance

I believe that thread408-135872: The top three sellers for butterfly valve? and thread408-210294: LNG Valves within this Forum (for example) should partially answer your questions.

I would still like to know who makes a high quality gate and globe for steam service. I am looking for something along the lines of Wm Powell. Reliability and longevity are my primary concerns. My client only gets funding for mechanical renovations every 25-30 years, but the funding is sufficient for a high-end product.

Velan manufactures many types of valves (at least Gate, Globe, Ball, Check and Tripple-Offset): are you referring to one or more types in particular, or are you speaking in general terms only?
Similarly, may I ask which valve brands from Tyco Group do you represent, in particular?
Do you find there are Tyco brands that are better or worse than the other ones, from a Repair Facility point of view?
Hope this helps, 'NGL

Velan makes good gate valves, however I have seen problems with their globe valves in the past (they also have less globe valve selection than other manufacturers).
'Tyco' is a broad term, I have seen good reliability from such tyco brands as Anderson-Greenwood, Crosby, Vanessa and Yarway, however I have also seen very poor reliability from Keystone valves.
Another consideration would be quality of vendor support for their product, however this can be difficult to quantify based on different reps in different regions of the world.
Hope this helps,
